Hartree方程散射算子的实解析性

On the Real Analyticity of the Scattering Operator for the Hartree Equation

Changxing Miao, Haigen Wu, Junyong Zhang

摘要:

本文研究了Hartree方程$ i\partial_tu=-Δu+u(V*|u|^2)$的散射算子的实解析性。为此,我们利用内部和外部切断的时间和空间,并结合紧性的论点,以克服困难所产生的缺乏良好的性质的非线性Klein-Gordon方程,如有限的传播速度和理想的时间衰减估计。此外,本文的方法还简化了Kumlin中具有立方非线性项的非线性Klein-Gordon方程散射算子解析性的证明.

英文摘要:

In this paper, we study the real analyticity of the scattering operator for the Hartree equation $ i\partial_tu=-Δu+u(V*|u|^2)$. To this end, we exploit interior and exterior cut-off in time and space, and combining with the compactness argument to overcome difficulties which arise from absence of good properties for the nonlinear Klein-Gordon equation, such as the finite speed of propagation and ideal time decay estimate. Additionally, the method in this paper allows us to simplify the proof of analyticity of the scattering operator for the nonlinear Klein-Gordon equation with cubic nonlinearity in Kumlin.
